Adhesive for partitions made of tongue-and-groove slabs. Do-it-yourself interior walls made of tongue-and-groove slabs. Preparation of mortar mixture

Installation of tongue-and-groove slabs is carried out using technology that has been used recently professional builders and home craftsmen increasingly. These products have low weight, reliable locking connections and convenient sizes. All this allows you to install them without much effort, remodeling the premises as required by personal preferences.

Types and features of tongue-and-groove products

Before you begin installing tongue-and-groove slabs, you need to understand what types of these products are on the market today. They are silicate and gypsum, the latter are made from the material of the same name, to which a plasticizing admixture is added. For the production of silicate, lump and also quartz sand, which are pressed and kept in an autoclave.

Which slabs to choose

If you want to give your walls heat-insulating qualities, it is better to prefer gypsum boards; they do not allow sound to pass through. However, silicate ones are able to withstand higher mechanical loads and also absorb less moisture. Tongue-and-groove slabs, which can be easily installed with your own hands, are environmentally friendly, so they can be used for furnishing residential premises. The materials are not flammable, do not rot, and do not emit into the atmosphere harmful substances and are not deformed. On sale you can find solid ones that can reduce the weight of masonry by 25%. If we talk about sizes gypsum boards, then they are equal to 500 x 667 x 80 mm. But silicate ones are more compact: 250 x 500 x 70 mm. Once you've dealt with everyone load-bearing structures, you can begin laying tongue-and-groove products, but this must be done before laying the finishing coating on the floor and carrying out finishing work.

Preparation of tools and materials

Installation of tongue-and-groove slabs is carried out after preparing a certain set of tools and materials. These products can be installed in the center of the room, as well as against a wall that goes outside the building or into a cold room. By forming double partitions, you can hide wiring, other systems and communications.

To divide a room into separate zones, you can use partitions, the height of which starts from 80 cm. For installation you will need:

• building level;
• adhesive composition;
• anchor dowels;
• gypsum mortar;
• putty knife;
• screwdriver;
• cement-sand mortar;
• Staples;
• felt seal;
• primer;
• hacksaw;
• rubber mallet.

Preparing the site

Installation of tongue-and-groove slabs begins with site preparation. To do this, you should check the evenness of the walls and floor where the products will fit. If there are defects such as sagging, then they should be removed by grinding. The walls and floor should also be freed from cracks and depressions, filling the errors with a cement-sand mixture.

As soon as the bases are dry, they should be coated with a primer. If you decide to install a partition during the ongoing repair process, then the contact lines should be marked on the floor and walls. After finishing coat cut along the markings so that the base can be seen. For paint, wallpaper, decorative plaster You cannot install slabs; this applies to laminate, parquet and linoleum. If the surfaces have decorative coating as ceramic tiles, then it does not need to be removed, but the surface is first checked for strength.

The installation of the tongue-and-groove slab must be carried out correctly; to do this, a cord should be pulled between the walls over the entire area, moving it 30 cm from the floor surface. This will allow you to control the vertical placement of the products. Along the contact line it is necessary to stick a sealant, the width of which must correspond to the thickness of the slab. In the role of this material You can use bitumen-impregnated felt or a cork backing.

Working on the first row

Installation of a tongue-and-groove slab cannot be called difficult work, however, it is necessary to approach this issue extremely carefully. To install the starting row of slabs, it is necessary to cut off the lower ridges using a hacksaw. Glue is applied to the seal, which must be on a vertical and horizontal surface. The first slab is installed on the side where it will adjoin the wall. The perforated bracket is inserted into the groove. The bracket should protrude a few centimeters above the slab. It is fixed to the wall with self-tapping screws, or this is true when you are working on a concrete base.

The slab should be facing upward with the groove, it is leveled and pressed against the base, tapping it with a mallet. In the place where the second slab will adjoin, it is necessary to install a piece of bracket and secure it with dowels to the floor. If it turns out that this product is installed unevenly, then the rest will repeat the angle of inclination. In this situation, it will not be possible to level the masonry; the interlocking connections will interfere. This explains the need to level the first slab of the bottom row. The composition is applied to the side grooves and ridges so that the seams between the plates are not thicker than 2 mm. Excess mixture should be removed with a spatula, checking the masonry building level. A bracket is installed in the lower part and fixed to the floor with anchor dowels. Each subsequent product must be installed after the adhesive composition has set on the previous one.

Installation of the following rows

Installation of walls made of tongue-and-groove slabs involves displacement of the seams in the second and subsequent rows. To ensure this condition, the slab must be cut in half. At the end and beginning of the row, staples should be fixed on the cuts. This must be done in the place where the sections adjoin the wall. The glue should be more liquid; it should be applied to the bottom and side grooves of each product. It is important at this stage to check the vertical and horizontal of the masonry. The next row is installed only after the glue has set in the second row.

Formation of the last row

Usually not accompanied by difficulties. However, it is important to pay attention to the entire process Special attention. For example, the top row should not be adjacent to the ceiling. Approximately 1.5 cm should be left between the plates and the horizontal surface. To do this, staples are installed in the upper grooves of the final row using glue and screwed to the ceiling with dowels. After installation is complete, the gap can be filled with foam, the excess of which is cut off after hardening.

Features of installation of Knauf brand slabs

Knauf tongue-and-groove slabs, the installation of which requires compliance with certain nuances, can be installed by a home craftsman independently. For example, when preparing, it is important to ensure that the subfloor where work will be carried out is stationary, level and stable. If there are unevennesses that exceed more than 10 mm, then it is necessary to form a leveling layer; this can only be done under the partition.

Before starting manipulations, the surface is cleaned of dirt and construction debris, as well as oil stains. To prepare the mixture, pour the dry composition into a clean plastic container with water. The liquid should be at room temperature. The composition is mixed using a drill with an attachment or an electric mixer. The solution is left for a few minutes and then mixed again. It is recommended to cook it in portions, one of which you can finish in the next half hour.

Such a tongue-and-groove gypsum board, which is often installed independently, can be installed in one of two ways. The first involves the use of glue, which is applied to concrete base. This method allows you to get a rigid fastening. The composition is applied to the floor and walls in an even layer, and average consumption for an 80 mm slab it will be approximately 2 kg per square meter. If the thickness of the partition increases to 100 mm, then the glue consumption will be equal to 2.5 kg.

The second method involves fastening to walls, ceilings and floors through an elastic cork gasket. This method allows for higher sound insulation, especially for impact noise such as door slams and knocking. Such products are laid with the ridge or groove up. It is more practical to install it on top with a groove, since in this case it is more convenient to lay the glue than to try to spread it on the ridge. If the ridge is located on top, then it should be removed using a hacksaw with large teeth. Sometimes elements are removed using a roughing plane until a smooth surface is achieved.

Features of installation of tongue-and-groove slabs of the Volma brand

The Volma tongue-and-groove slab, which is installed using the same technology as described above, is a product total area which is equal to 0.33 m 2. The plate is made from hydrophobic and plasticizing additives, which are complemented by lithium technology during the manufacturing process. Products are intended for forming partitions in rooms and buildings for various purposes with a normal and dry microclimate.

You can control the resulting plane by applying a rule or a regular strip to the wall under different angles. If necessary, the plane can be adjusted until the glue sets. It is important to ensure that the slabs are glued together at four ends. Any excess compound that appears must be rubbed down with a spatula before sealing the seam. You should not begin laying the second row until you have measured the remaining gap for which the section is being prepared. The additional element will become the beginning of a new row. This will allow the vertical seams to spread apart.

You will be able to install tongue-and-groove slabs with your own hands; the tips presented in the article will help you with this. From them you can learn that the slabs must be laid down from the sides and from above; they must be used for this only so as not to damage the blocks. This rule should not be neglected, since otherwise it will not be possible to achieve a tight connection between the tongue and groove.

Adhesive for tongue-and-groove slabs "Fugen"

If you decide to purchase glue for installing tongue-and-groove slabs, then you can pay attention to the “Fugen” mixture, which is offered by the Knauf company. It should take approximately 1.5 kg per square meter. If joints between sheets of drywall are sealed, the consumption will be 0.25 kg. This mixture is a dry composition, which is made on the basis of gypsum and polymer additives.

The solution is intended for sealing seams and cracks. To prepare the dry mixture, pour it into a container with cold water. For 1.9 liters of water you will need 2.5 kg of composition. After evenly distributing the dry mixture, it is necessary to hold it for 3 minutes and mix until a homogeneous mass is obtained. Its consistency should resemble thick sour cream.

Conclusion

If, when laying a partition, you plan to make a window or doorway, then you need to think about the technology for attaching the slabs above it. If the opening has a width not exceeding 80 cm, then the product can be installed on a box or temporary support. This is true provided that there is one row of blocks per opening. If the width is greater than the specified value or there are several rows, then it is necessary to form a strong jumper.

The solution is in working condition for at least 1 hour (at a temperature of +20 C).

Substrate preparation, application.

Before gluing tongue-and-groove boards, plasterboard or other building panels to the base, it is necessary to prepare it: clean it of substances that weaken adhesion. Dust and grease should be removed glossy surface sand, smooth out significant unevenness with finishing materials and putty. Surface - drywall or others finishing panels- It is recommended to treat with a primer.

When installing partitions and walls using gypsum boards (GGP), a gypsum adhesive solution is applied to the base of the slab installation or to the ridge side of the slab using a spatula. The slab is placed on the glue, and it is aligned relative to the markings made or the plane of the wall using a level and rules. Plates connected to each other glue solution subject to adjustment within 10 minutes. When sealing slab joints, excess gypsum mortar appears between the seams, which must be removed with a spatula and subsequently used to seal the seams.
